Phlox plant named ‘Valentina’

ABSTRACT

A new and distinct cultivar of  Phlox  plant named ‘Valentina’, characterized by its upright plant habit; freely flowering habit; soft pink-colored flowers; and good cut flower and garden performance.

Botanical designation: Phlox paniculata.

Cultivar denomination: ‘VALENTINA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox, botanically known as Phlox paniculata and hereinafter referred to by the name ‘Valentina’.

The new Phlox originated from a cross-pollination of two unnamed proprietary selections of Phlox paniculata, not patented. The new Phlox was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Hillegom, The Netherlands in July, 2004.

Asexual reproduction of the new Phlox by cuttings in a controlled greenhouse environment in Hillegom, The Netherlands since 2006, has shown that the unique features of this new Phlox are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phlox have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Valentina’. These characteristics in combination distinguish ‘Valentina’ as a new and distinct cultivar of Phlox:

-   -   1. Upright plant habit.     -   2. Freely flowering habit.     -   3. Soft pink-colored flowers.     -   4. Good cut flower and garden performance.

Plants of the new Phlox and the parent selections differ primarily in plant height and flower color.

Plants of the new Phlox can also be compared to plants of Phlox paniculata ‘Starfire’, not patented. In side-by-side comparisons conducted in Hillegom, The Netherlands, plants of the new Phlox and ‘Starfire’ differed primarily in flower color as plants of ‘Starfire’ had bright red-colored flowers. In addition, plants of the new Phlox were shorter than plants of ‘Starfire’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Phlox, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phlox.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Hillegom, The Netherlands, under commercial practice during the late summer and early autumn in an outdoor nursery with day temperatures ranging from 14° C. to 32° C. and night temperatures ranging from 5° C. to 15° C. Plants had been growing for two years when the photographs and description were taken.
